The ubiquitous 555 timer, (hooked up for variable mark/space ratio, if you build one you`ll find out why it`s needed), and a couple of D type flip-flops, (4013), to provide the count for the ULN2003 stepper motor driver. (ULN2003`s might be hard to find off.... -
A better way to make a stepper motor controller is to make a printed circuit board, and then simply drop the components in. After making the PCB, placing the components and soldering them hardly takes any time at all, in contrast to the proto board which.... -
This is a very good integrated circuit. There is no need for any external glue logic to drive the circuit, there is only 2 pins to drive the motor, one for controlling the direction and the other to trigger the stepping pulses. It provides a very compact.... -
M1 is a stepper taken from an old disk drive. There are five pins, i. e. , common, coil 1, 2, 3 and 4. Resistance measured between common pin and each coil is about 75 Ohms. Driving current for each coil is then needed about 60mA at +5V supply. A Darlington.... -
To build astepper motor tester, the circuit contains two sets of drivers that can support both unipolar and bipolar stepper motors. The control circuit and driver circuit are in separate power supplies that can work on a wider rangeof different power.... -

Here`s the new flasher circuit schematic. It consists of a 555 timer circuit and a power transistor. The power transistor is probably way overkill, (it is rated at 10A) but it`s what I had available. You can vary C1, R1 and R2 for to vary the flash rate and.... -
Using PC`s parallel port is a convenient way to control a stepper motor. For unipolar stepper motors, up to two motors can be controlled with the 8bit data line. The standard way of connecting a unipolar stepper motor to the parallel port is to use a.... -
The drive circuits for Unipolar stepper motors are usually very simple. In its simplest form, a transistor or MOSFET is used to drive each section of the windings. With this design, the control signal must be supplied programmatically to the four windings of.... -
Stepper motors are available in several versions and sizes with a variety of operating voltages. The advantage of this general-purpose controller is that is can be used with a wide range of operating voltages, from approximately 5 V to 18 V. It can drive the.... -
Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal (from a square wave generator) into signals with a 90-degree phase difference, which are required to drive the stepper motor windings. The price we pay for the.... -
Based on the SN74LS194 - Bidirectional Universal Shift Register the circuit is designed to drive UNIPOLAR type stepper motors and provides only basic control functions - Forward, Reverse, Stop and Speed adjustment. For the purposes of this page the direction.... -
The L298N driver module contains the ST` L298N chip, ususlly used to drive two 3-30V DC motor, there is a 5V output interface, power for 5V single-chip circuitry, support 3. 3VMCU control. With it, you can control the DC motor easily. You can get the diagram.... -
For maximum efficiency, set MAX_STEPPERS equal to the number of stepper motors that you are controlling (but never more than 4). Motors are referred to by their indices 0, 1, 2 and 3. On the QCard there is a trade-off between the number of motors being.... -
Attached are 3 captures from my L297/L298 board using the same motor at 500, 750 and 900 steps/sec on a 36v supply, wired bipolar parallel (coil resistance = 3. 2ohm). This shows the A-enable signal (blue) and the sense voltage (red). The sense voltage is.... -
